Being induced means your healthcare provider uses medical techniques to start labor artificially rather than waiting for it to begin on its own. It’s one of the most common interventions in childbirth: more than one-third of all singleton births in the United States in 2024 (34.5%) involved labor induction, up 39% from 2016. If your provider has mentioned induction, or you’re trying to understand what a friend or family member is going through, here’s what the process actually involves and what to expect.
Why Inductions Happen
The primary reason for induction is a concern about the health of the pregnant person, the baby, or both. Your care team may recommend it for a wide range of reasons, including:
- Going past your due date. If labor hasn’t started on its own one to two weeks after the due date (42 weeks from the last period), continuing to wait raises risks for the baby.
- High blood pressure or preeclampsia. These conditions can worsen quickly and threaten both mother and baby.
- Diabetes. Whether it developed during pregnancy (gestational diabetes) or existed before, uncontrolled blood sugar can affect the baby’s growth and delivery safety.
- Water breaking without contractions. If the amniotic sac ruptures but labor doesn’t follow, the risk of infection increases.
- Problems with the baby’s growth. If the baby isn’t growing as expected, or there’s too little amniotic fluid, delivering sooner may be safer than waiting.
- Other medical conditions. Kidney disease, heart disease, uterine infections, or a BMI of 30 or higher can all factor into the decision.
Induction isn’t always medically urgent, though. Some people choose an elective induction at 39 weeks. A large trial called ARRIVE found that healthy first-time mothers induced at 39 weeks were actually less likely to need a cesarean delivery (18.6%) compared to those who waited for labor to start naturally (22.2%). The induced group also had lower rates of pregnancy-related blood pressure disorders and reported less pain during labor.
How Your Cervix Gets Assessed First
Before induction begins, your provider checks how ready your cervix is using something called a Bishop score. This scoring system looks at five factors, including how dilated and softened your cervix is, and assigns a number from 0 to 13. A score of 8 or higher means your body is already close to labor and induction is more likely to go smoothly. A score of 6 or 7 is borderline. A low score means your cervix needs more preparation, which is called “ripening,” and that adds time to the process.
Methods Used to Start Labor
Induction typically involves one or more of the following approaches, depending on how ready your cervix is.
Cervical Ripening
If your cervix isn’t dilated much, your provider will often start by softening and opening it. One common method is a Foley bulb (also called a cervical ripening balloon). A small catheter is inserted through the vagina into the cervical opening, then a tiny balloon at the tip is inflated with about 2 ounces of saline. The pressure from the balloon encourages the cervix to dilate. Sometimes that pressure alone is enough to break the water. Once the cervix opens sufficiently, the balloon falls out on its own.
Medications that mimic natural hormones called prostaglandins can also be placed near the cervix to soften it. These are sometimes used alongside or instead of the balloon.
Breaking the Water
If the amniotic sac is still intact and the cervix has opened enough, your provider may rupture it manually. This is a quick procedure done during a cervical exam. Releasing the fluid often intensifies contractions or helps get them going.
Synthetic Oxytocin
Oxytocin is the hormone your body naturally produces to drive contractions. A synthetic version is given through an IV to either start contractions or make them stronger and more regular. The dose is typically started low and gradually increased until contractions are coming in a consistent pattern. This is often the final step after cervical ripening has done its job.
Membrane Stripping
This is sometimes done in your provider’s office before a formal induction. During a cervical exam, your provider sweeps a finger along the membranes that connect the amniotic sac to the uterine wall. This releases natural prostaglandins and can nudge labor to start within the next day or two. It’s not always effective, but when it works, it can reduce the need for a full hospital induction.
How Long Induction Takes
This is one of the biggest surprises for many people: induction is not fast. The early phase of labor alone can take 24 hours or longer, especially for first-time mothers. If your cervix needs ripening first, add several more hours to that timeline. From the first intervention to delivery, the entire process can stretch well beyond a full day.
The timeline depends heavily on your Bishop score at the start. Someone whose cervix is already soft and partially dilated may progress in a matter of hours once oxytocin starts. Someone starting from a completely closed cervix may spend 12 or more hours on cervical ripening alone before contractions even begin in earnest. Knowing this ahead of time helps you plan. Bring entertainment, snacks (if your hospital allows them), and comfortable clothes for the early hours of waiting.
What Contractions Feel Like During Induction
Contractions from synthetic oxytocin can come on stronger and closer together than the gradual buildup many people experience with spontaneous labor. In natural labor, contractions usually start mild and slowly ramp up over hours, giving your body time to adjust. With induction, contractions can go from nothing to intense in a shorter window, which is why many people who are induced choose an epidural earlier in the process.
All the same pain management options available during spontaneous labor are available during induction. You’re not locked into any particular approach just because your labor was started artificially.
Risks to Be Aware Of
Induction is generally safe, but it does carry some considerations. Because synthetic oxytocin can cause contractions to come too frequently, your baby’s heart rate will be monitored continuously. If contractions are too close together, your provider can lower or pause the medication. This close monitoring does mean you’ll be more tethered to the bed than you might be during unmedicated spontaneous labor, though some movement is usually still possible.
Induction also means a longer hospital stay overall, since you’re arriving before labor has started rather than showing up already in active labor. For some people, the process doesn’t result in enough cervical change or the baby doesn’t tolerate the contractions well, and a cesarean delivery becomes necessary. That said, the ARRIVE trial showed that for healthy first-time pregnancies at 39 weeks, induction actually lowered the cesarean rate rather than raising it.
What the Day Looks Like
Most scheduled inductions begin with a planned arrival at the hospital, often in the evening or early morning. After checking in, you’ll be placed on a fetal monitor and have an IV started. Your provider will examine your cervix, determine your Bishop score, and choose the starting method based on how ready your body is.
If cervical ripening is needed, that phase often runs overnight. Many people try to sleep through it, though the discomfort from the balloon or early cramping can make that difficult. Once the cervix has opened enough, your provider may break your water and start the oxytocin drip. From there, labor progresses more like any other birth: contractions build, you manage pain however you’ve planned to, and eventually you push.
The key difference is the front-loaded waiting. Once active labor kicks in, the pushing and delivery phase is no different from spontaneous labor. Most people who’ve been through induction say the hardest part was the patience required during those early hours, not the labor itself.
